Self-ligating versus Invisalign: analysis of dento-alveolar effects

The aim of this study was to evaluate the changes in the transverse dimension and the perimeter of the maxillary arch produced by low friction self-ligating brackets TIME 3 compared to the Invisalign technique. Materials and methods. Both the self-ligating sample and the Invisalign group were composed of 20 subjects, evaluated at the beginning (T0) and at the completion of therapy (T1). All subjects presented a Class I malocclusion with mild crowding in a permanent dentition, without craniofacial anomalies, missing teeth or a history of many patients not wanting to show metal or partially clear orthodontic treatment. Dento-alveolar measurements fixed appliances with arch wires when they smile. Significant differences between the treated groups were assessed with Independent Samples t test (p<0.05). Results. To this date, little clinical research has been published to self-ligating sample and Invisalign group were recorded comprehensively study the effectiveness of Invisalign treatment (1-3). No significant changes were found for CWL, MWF, MWL, and AD values. There was not a statistically significant difference between the treatment durations appliances. These data suggest that Invisalign treatment cannot be somewhat faster than fixed appliances. Moreover the final occlusion might not be as ideal.
